BACKGROUND: Surgical treatment of adolescent hallux valgus has been a challenging intervention because of high rates of postoperative recurrence. The purposes of this study were to describe a proximal abduction-supination osteotomy of the first metatarsal and prospectively review preliminary results of this procedure for correction of adolescent hallux valgus.
METHODS: Eleven patients (12 feet) who had had a proximal abduction-supination osteotomy of the first metatarsal combined with a distal soft-tissue procedure to correct an adolescent hallux valgus deformity were prospectively reviewed clinically and radiologically. The average duration of follow-up was 22 months. The average age at the time of surgery was 17 years.
RESULTS: The mean score on the Japanese Society for Surgery of the Foot standard rating system for hallux improved significantly, from 62.0 points preoperatively to 99.2 points postoperatively (p = 0.002). All patients were satisfied and would choose to have the same procedure again. The mean hallux valgus angle decreased significantly, from 32.3° preoperatively to 12.2° postoperatively (p = 0.002); mean intermetatarsal angle decreased significantly from 14.0° preoperatively to 6.2° postoperatively (p = 0.002). No feet had postoperative recurrence of hallux valgus (a hallux valgus angle ≥20°). There were no occurrences of nonunion or transfer lesions.
CONCLUSIONS: The clinical and radiological results of this study demonstrate that a proximal abduction-supination osteotomy with a distal soft-tissue procedure, which described in this study, achieved significant correction of an adolescent hallux valgus deformity, significant improvement in pain and function, and reduction in rate of recurrence.
